This is in fact a topic on which many have have been thinking.  You raise a 
number of interesting issues.
1)  Neither Dawkins, nor E.O.Wilson, nor most of the other so-called "genetic 
determinists" have claimed that genetic predisposition is the end of the 
matter.  Yes, human beings have to pay attention to genetically determined 
modes of behavior, but no, that's not all we are.  We are, indeed, different 
from other animals.  We think.
For that reason, actions to drastically reduce the total population of the 
Earth, violating the "selfishness" of our own particular gene packets, are 
both rational and, I hope, possible.  We can see beyond both the narrow 
behavioral patterns of gene propogation, and even the mathematics of kinship 
altruism, and act on behalf of the planet as a whole.
2)  Of course, this isn't easy.  Even if our goals are global, our actions 
and payoffs are still local.  It is on this level that population reduction 
strategies must focus.
My own proposal -- impossible to impliment of course -- is that everyone be 
"reversably steralized" some time before puberty.  Then, if two people wish 
to have a child, they can get the process reversed.  The conceptual advantage 
of this is that childbearing becomes a positive choice, instead of the lack 
of the negative choices Ike mentions.  The drawbacks are all practical:  it 
must be simple, cheap, reliable, and universal.  The other choice facing us 
all is wholesale famine, plague, and bloodshed, combined with worldwide 
ecological disaster.  What fun.
